INTERNATIONAL RTTY FREQUENCY LIST
ISSUE 11 1987
CREATED & EDITED BY K9EUI
_________________________
This list of RTTY stations contains over 1000 personal loggings
by a few dedicated individuals. No information in this list was
copied from other lists.
Frequency is listed in kHz with L or U to indicate lower (normal)
or upper (reverse) sideband mode for normal copy. Frequencies are
within 2 kHz.
Shift is rounded off to the nearest standard shifts of 85, 170,
425 or 850 Hz.
Speed is given in bauds rather than wpm. All stations in this list
transmit either standard "Baudot" or SITOR code. A letter following
the baud means a press station that sends in (E) English or (F)
foreign language (at times). (M) indicates a frequency division
multiplex (FDM) transmission, usually carrying AP/UPI news on one
subcarrier.
See the addendum for description of the service abbreviations.
It is sometimes difficult to distinguish between DIPLO and CRYPTO
stations, since most are probably ministry/embassy/govt stations.
CRYPTO transmissions are usually 5 letter groups, sometimes 5
digit groups. Some of these stations bounce back and forth between
crypto and plain text. Some of the E. German stations are switching
to SITOR. The Prensa Minrex (PM) stations switch from Spanish to
gibberish (some form of encryption) not formed into groups.
Synoptic weather transmissions are often confused with crypto since
they are in the form of groups of characters, mostly numerals.
Most stations do not identify when sending traffic, but do when
first coming on the air to test. Some stations use the same call
on many frequencies, while others have a separate call for each.
there have been a few E. German MFA stations running 100 baud
(132 wpm).
The Reagan administration has cut expenses by removing the HF
National Weather Bureau stations from service. These stations,
known as WBR70, operated "L 850 74" on 3223, 3235, 4062, 5925,
7930, 8105, 8130, 8140, 10950, 12175, 13624, 14853, 16440, 18675,
and 18765 kHz. I mention it here in case some of them reappear.
The PL stations in Cuba also carry TASS at times.
The Voice of America operates several "programs" at once and
are as follows:
Program Freqs.
1 5435, 12224, 13770
2 5460, 6941, 9855, 10972
3 7443, 7478, 10880, 13995, 15749, 15750, 15875
4 20483
5 14525
U.S. State Dept. news (ARF) is found simultaneously (1630Z) on
14638, 18543, 22782, and 23770 kHz.
MARITIME SITOR OPERATION
All SITOR operation is 170 shift (LSB). When not sending
traffic, most stations run a CW ID tape keyed on the space
frequency. Some foriegn stations send a burst of FEC (mode B)
data rather than the CW ID. SITOR is the same as AMTOR used
by amateurs.
SITOR frequencies are roughly as follows:
COAST STATIONS SHIPS
FREQ (chan) to FREQ (chan) FREQ to FREQ
4350 (401) 4357 (415) 4140 4160
6492 (601) 6506 (629) 6230 6280
8705 (801) 8718.5 (828) 8300 8360
13071.5 (1201) 13100.5 (1259) 12490 12520
17197.5 (1601) 17232.5 (1671) 16660 16700
22561.5 (2201) 22595 (2268) 22112 22185
Traffic lists, weather and emergency info are sent FEC (mode B)
and traffic and news is sent ARQ (mode A). Some maritime activity
is listed as follows:
WLO has 4 daily FEC broadcasts at 1530, 1130, 1730, and 2330Z.:
FREQ CHAN
4352 405
8707 805
13083.5 1225
22588 2254
Other FEC broadcasts heard:
STATION FREQ TIME
VCS 4353/6497.5 0215
JFA 13074.5 1800
FFL 13075 ?
KLC 4354 0300
NMF 8710.5 0400
NMF* 8490/13083 1700/0200
16986.8
NIK 5320/8502 0018
NIK 12570 1218
WCC 4356.5 0030
* Also look for NMF on 17203 and 22567.
AP / UPI press can be copied on many stations, especially
between 2300 and 0100Z (ARQ).
Other stations using SITOR include WLO, VCS, GKP, WCC, GKE,
WSL, WNU, WPD, KPH, KFS, UFN, NMN, HKB, TIM, OST, LGB, VIS,
IAR, PCH, GKQ, and DCF.
